Installing Roadmaster Battery Charge Line Kit on 2018 Jeep Cherokee

Question:

How does the charging cable hook up to the motor home and to the tow vehicle. What else do I need besides the kit.

It sounds like you are referring to the Roadmaster Battery Charge Line Kit # RM-156-25 for your 2018 Jeep Cherokee. This kit allows you to connect your Jeep's battery to the 6-Way or 7-Way plug at the front of the vehicle so that up to 15 amps from the RV's battery can be used to maintain its charge while being towed. If no charge line is present in your RV, you will also need to add the Motor Home Charge Line Kit # RM-156-75.

For the charge line kit, you will attach the included length of red 14 gauge wire to the center pin in the Jeep's connector. You will then route the wire to the Jeep's battery, choosing a route that will avoid the possibility of a short circuit or other damage to the vehicle. The wire should be covered with the included split loom.

From there, if you need to use the Motor Home Charge Line kit # RM-156-75, you will attach one end of the included length of red 12 gauge wire to the charge line pin in the RV's connector. Then route the wire to the area of the positive battery terminal on the RV and connect using the provided circuit breaker.

I have attached a couple installation videos for these kits that you might also find helpful.
